x and y intercepts

Front

What is the x-intercept of a function?

Back

The x-intercept is the point where the graph of a function crosses the x-axis, which occurs when y = 0.

Front

What is the y-intercept of a function?

Back

The y-intercept is the point where the graph of a function crosses the y-axis, which occurs when x = 0.

Front

True or False: The x-intercept of a function ALWAYS occurs where y is equal to zero.

Back

True

Front

Given the ordered pairs (8,10), (3, -4), (0, 8), (4, -3), (9, 0), what is the x-intercept?

Back

(9,0)

Front

Which ordered pair could represent a y-intercept on a graph?

Back

(0, 4)

Front

Identify the x-intercept of the linear equation -3x + 2y = -24.

Back

(8, 0)

Front

Solve for y: -4x + 12y = -36.

Back

y = \frac{1}{3}x - 3

Front

What does it mean if a function has no x-intercept?

Back

It means the graph of the function does not cross the x-axis, indicating that the function does not have any real solutions for y = 0.

Front

How can you find the x-intercept from a linear equation in standard form?

Back

To find the x-intercept, set y = 0 in the equation and solve for x.
